(Still haven't had my coffee yet) Perhaps I forgot to reference the "ps - illegal instruction" thread in my original thread - my apologies. Nested virtualization is *not* the point or objective of the exercise - enabling installation of Debian in W7VPC *is*. Hypervisor is a very common "exception" in my experience - I guess it depends on what you're exposed to in the workplace.
